Python 2.5.1 (r251:54863, Jul 16 2007, 10:57:41) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-42)] on linux2 Type “help”, “copyright”, “credits” or “license” for more information. >>> import MySQLdb Traceback (most recent call last): File ““, line 1, in File “build/bdist.linux-i686/egg/MySQLdb/__init__.py”, line 19, in File “build/bdist.linux-i686/egg/_mysql.py”, line 7, in File “build/bdist.linux-i686/egg/_mysql.py”, line 6, in __bootstrap__ ImportError: /root/.python-eggs/MySQL_python-1.2.2-py2.5-linux-i686.egg-tmp/_mysql.so: undefined symbol: compress >>>

出现问题的原因：在编译的时候没有加载zlib。 问题的解决：
1、rm build -rdf ：删除build目录，使得运行setup.py build的时候会重新编译。
2、运行python setup.py build,在最后一行会看到如下的信息：
gcc -pthread -shared build/temp.linux-i686-2.5/_mysql.o -L/data2/mysql/lib -lmysqlclient_r -lpthread -lcrypt -lnsl -lm -lpthread -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv -o build/lib.linux-i686-2.5/_mysql.so
把上述信息复制然后在编译语句的最后添加 -lz 重新编译_mysql.so 运行：gcc -pthread -shared build/temp.linux-i686-2.5/_mysql.o -L/data2/mysql/lib -lmysqlclient_r -lpthread -lcrypt -lnsl -lm -lpthread -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv -o build/lib.linux-i686-2.5/_mysql.so -lz

3、运行python setup.py install即可。
这是再import MySQLdb的时候就不会报错啦。
